The experiment aimed to study cucumber response and nutrient uptake under different nitrogen, phosphorus and potassium combination levels, and to determine the proper nitrogen, phosphorus and potassium nutrient requirements for growing cucumber crop in sand culture under plastic houses. This study concerned about the importance of interactions among N, P and K in the production of cucumber crops under plastic house conditions to improve the nutrient balance for optimum plant growth and yield. Total yield and total number of fruits per plant were increased with the increase of N, P and K levels. Low nitrogen level 90 mg/l, with different phosphorus and potassium combination levels, is not suitable for cucumber plants allover the season; medium nitrogen level is, however, suitable till the second week after harvest. In contrary, low phosphorus and potassium levels were suitable till on second week after harvest; later on, plant tissue contents declined sharply accompanied with decreases in vegetative growth and yield till the end of the season.
This work laid main emphasis on productivity of apple as influenced by water and nutrient management particularly in Himalayan region. As apple plays an important role in the economy of Himalayan people. Acute water shortage during critical growth stages has drastically affected the apple productivity. Erratic monsoon behaviour from last one decade further aggravates the problem. The results being declining apple production to almost 50 per cent during 2009-10 and about 30 per cent in 2012-13 (current year). This needs a water and nutrient management to sustain future apple production in the region.
This book provides a broad outline of drip fertigation in rice. Rice crop requires very large amount of water under the traditional flood irrigation method. However, due to growing demand in the domestic and industrial sectors, water is becoming increasingly scarce, and there is a need to develop ‘water saving irrigation techniques’ that require less irrigation water than the traditional methods. The need to produce more rice with less water is crucial for food security for many Asian countries. Addressing these issues requires an integrated approach to soil – water – plant - nutrient management at the plant - rooting zone. One of these technologies is fertigation, which is the direct application of water and nutrients to plants through drip irrigation system, which accelerates the pace of rice production by drip fertigation in rice. The book would prove useful to research scientists for water management in rice.
Cucumber (Cucumis sativus L.) is one of the most important fruit crops with lots of health values. The versatility of this fruit has made it a clear favorite in dish ingredients. Due to the ever increasing world population the demand on cucumber has increased drastically. The farming community worldwide has always found it difficult to cater its consumption. The book was written with the aim of increasing the growth and yield potential of cucumber. Dr. Sumathi has conducted field experiments at the Department of Vegetable Crops, Horticultural College, TNAU, Coimbatore, Tamilnadu, INDIA to elucidate the effect of shade and fertigation on growth, yield and quality of cucumber hybrid ‘NS 404’. Based on these experiments, it was revealed that the fertigation treatments with 100 per cent water soluble fertilizers applied in combination with calcium chloride spray registered the maximum yield and growth values. The improvements were found in terms of morphological, physiological, biochemical characteristics, enzyme activities and also factors such as fruit weight and fruit yield. This analysis was performed to help the farming community worldwide to increase their cucumber yield.
Shorea robusta Gaertn. f. (Sal) forests cover over 11 million ha in India, Nepal and Bangladesh.These forests are conventionally managed for timber. Recently, interest in producing multiple products from sal forests has increased. Associates of sal are known to produce edible fruits, fodder and compost, fibers, leaves for umbrellas, medicinal plants, thatch, grass, brooms and many other products depending on the species composition. These forests will continue to provide all these products if managed in a scientific and sustainable manner. Sustainable management of forest resources is increasingly seen to be the most important conservation strategy for majority of the harvest species and their habitats. This Book provides an approach to manage the wild resources of medicinal plants in such a manner as to ensure the attainment of continued satisfaction of human needs for present and future generations.
Medicinal herbs are moving from fringe to mainstream use with a greater number of people seeking remedies and health approaches free from side effects caused by synthetic pharmaceuticals. International market of medicinal plants is over US $60 billion per year, which is growing at the rate of 7 per cent. Coleus forskohlii is one of the most potential medicinal crops of the future as its pharmacopical properties have been discovered only recently. Forecasts of the requirements of forskolin for drug development indicated the need for a sustained supply of root material in quantities that would threaten the survival of the species in nature. Irrigation and fertilization are the most important management factors through which farmers control plant development, yield and quality. This book deals with the detailed review of irrigation and fertilizer management in Coleus forskohlii and other medicinal crops, effect of drip and fertiligation schedules on yield and quality of Colues forskohlii.
Research work was undertaken in grafted brinjal (Solanum melongena L.) to standardize spacing and fertigation levels. Brinjal grafts were compared with seedlings (non grafted brinjal) under main crop evaluation. After six months, the plants were pruned to obtain ratoon crop which was evaluated further.Based on this study, cultivation of brinjal grafts under 1 m x 1 m spacing and 100 per cent RDF (200:150:100 kg NPK ha-1) through fertigation proved its superiority for high remuneration than cultivation of brinjal seedlings both in main and ratoon crops.
A plant nutrition requirement and management is becoming the most burning issue in agro-industry. soil hosts for different microbes which has the potential to convert the inorganic form of nutrients to plant usable organic form. Artifical induction of microbes helps the plants to combat different stresses. Wate materials contains clossal amount of organic and inorganic nutrients which can be used by plants after processing (compost). The objective of this research to combat water stress by using compost and ACC-Deaminase technology
Cucumber is an important cucurbitaceous crop, which play an important role in our diet, due to its high nutritive value. The area and productivity of cucumber is very low, hence to maximize the production per unit of water use, adequate and timely supply of water is crucial one. Protected cultivation is frequently adopted for obtaining higher yield per unit area. The present investigation aimed with specific objectives to work out the water requirement of cucumber under shade net house, to study yield response of cucumber to different shading percentage of shade net and fertigation, to compute water use efficiency, fertilizer use efficiency and to work out the cost economics of cucumber cultivation in shade net house. Thus, the overall findings revealed that, maximum yield of cucumber Var. Gypsy, can be obtained by cultivating the crop under shade net with NPK through drip system.
A survey indicated that whitefly appeared to be the most challenging pest of tomato and almost all the farmers of study site in field experiment, five treatments with four replications were used. The trade name of the treatments were: i) Lancer gold (1.8% S.P) @ 2 ml/liter of water ii) Imadigold (17.8% S.L) @ 1.5 ml/8 litre of water iii) Alwin XL @ 2.5ml/litre of water iv) Alti-neem (0.03EC a.i.%) @ 3 ml/litre of water and v) untreated control. Among the treatments Imadigold application, reduced the number of whitefly population much more than other treatments as compared to control (about 70%). About 33% more fruit yield was obtained from the plot treated with Imadigold as compared to control plot. Therefore, in comparison to other treatments, Imadigold treatment was much more effective in term of whitefly management and on the tomato fruit yield in the study area.
This study is the first in Egypt to quantify the effect of using different fertigation treatments on wheat and maize grown in sandy soils. Furthermore, simulation of the effect of climate change was done and fertigation was considered as an adaptation option. Simulation of the effect of fertigation under climate change revealed that yield losses could be reduced under newly reclaimed soils for both crops when it was used. Furthermore fertigation could be considered as an appropriate irrigation management under climate change.
Cucumbers are used as salad, for pickling, are even consumed raw. Cucumber are also known for there medicinal values and are used in ayurvedic treatment for many diseases. In India cucumbers are grown both for domestic and export purpose but farmers are facing constant problem posed by insect pests which greatly reduce quality and quantity of produce incurring heavy losses.
