An investigation to evaluate the effect of foliar application of potassium and its spray schedule on yield and yield parameters in sweet orange cv. Jaffa was undertaken at experimental orchard, Department of Horticulture, CCS Haryana Agricultural University, Hisar during the year 2014-15. The results revealed that the foliar application of potassium nitrate at the rate of 2 and 4 % and potassium sulphate at 1.5 and 3.0 % significantly improved average fruit weight, fruit diameter, percentage of medium and large fruits, and fruit yield of sweet orange cv. Jaffa over control (water spray). The trend was vice-versa on the percentage of small fruits. The number of fruits per plant could not differ significantly due to various treatments. Among K sources and doses, foliar application of KNO3 at 4 % exhibited superiority over other treatments with respect to yield and yield parameters followed by KNO3 at lower dose (2 %) or K2SO4 at higher dose (3 %). Among various spray schedules, application of three sprays of K in the last week of April, May and August were found superior or at par in improving yield and yield parameters with 2 sprays in the last week of April and August. The fruit yield was recorded the highest (76.90 kg/plant) with a combination of the foliar application of KNO3 at 4 % and 2 sprays in the last week of April and August which was non-significant with KNO3 with an additional spray in the last week of May. The findings signify the importance of K spray in improving yield and yield parameters of sweet orange under semi-arid climatic conditions of north western India.

A field study was undertaken to extrapolate the impact of foliar application of potash and its spray schedule on yield and physical and chemical parameters of sweet orange cv. Jaffa at experimental orchard, Department of Horticulture, CCS Haryana Agricultural University, Hisar. The results revealed that foliar application of KNO₃ at both the doses (2 and 4%) was found significantly or marginally better than K₂SO₄ (1.5 and 3.0%) and control (water spray) in increasing the juice content. Peel content, peel thickness and rag content was found to be influenced significantly due to different treatments on K and its spray schedule. Minimum rag content (38.11%) was recorded with foliar application of KNO₃ at the rate of 4% and maximum with control. Ascorbic acid and acidity were found maximum with two foliar applications of KNO₃ at the rate of 4% in the last week of April and August. Foliar application of KNO₃ at the rate of 4% was found most effective in increasing yield of sweet orange over control and other K treatments. Spray of K in the last week of April, May and August was found superior in increasing yield closely followed by two sprays in the last week of April and August. The findings signify the importance of K spray in enhancing yield and quality of sweet orange under semi-arid north western conditions of India.

The present paper, as regards its subject-matter though not in form, is part of a general investigation of the rainfall of India, which has occupied much of my spare time for some years past, and the results of which are already partly embodied in a memoir which I hope, in the course of a few months, to issue as an official publication of the Indian Meteorological Office. The idea that the snowfall of the Himalaya exercises a direct and important influence on the dry land winds of North-Western India is not now put forward for the first time. It has been the subject of frequent reference in the annual reports on the meteorology of India since 1876, as well as elsewhere; and in a report on the administration of the India Meteorological Department lately issued, I summarised very briefly those points in the experience of the previous five years which have seemed to justify its provisional adoption as a basis for forecasting the probable character of the monsoon rains. Relying on this experience, in the month of June last, I put forward in the Government Gazette, a note giving warning of the probability of a prolonged period of drought in the approaching monsoon season, and the result, if not in exact accordance with the terms of the forecast, has been so far confirmatory of the general idea, as to induce me to put the facts of past experience formally on record, and thereby challenge attention to the subject. If I am right in the inference that the varying extent and thickness of the Himalayan snows exercise a great and prolonged influence on the climatic conditions and weather of the plains of North-Western India, it is probable, that with more or less modification according to the local geography, causes of a similar character will be found equally operative in other regions, and perhaps on an even more extensive scale.

The experiment was carried out during the spring and summer seasons of the year 2017-18 and 2018-19 at the Horticultural Research Farm, AAU, Anand to study the “Effect of soil and foliar applications of micronutrients on flowering and yield of mango variety”. The experimentcomprised of 13 treatments of different micronutrients application viz. FeSO4 100 g, ZnSO4 100 g, Borax 100 g and multimicronutrients grade-V 400 g as a soil application; FeSO4 0.5 %, ZnSO4 0.5 %, borax 0.2 % and multimicronutrients grade-IV 1.0 % as a foliar application and its combinassions and control (water spray). Soil application was done at second fortnight of September and foliar sprays of treatments were done at flower bud initiation, full bloom stage and pea stage initiationon 18 years old mango tree cv. Mallika. Experiment was laid out in a Completely Randomized Design (CRD) with three repetitions. Numbers of staminate, hermaphrodite and total number of flowers per panicle were found significant with respect to various micronutrients treatments during both the years of experiment. Maximum staminate flowers per panicle, hermaphrodite flowers per panicle and total number of flowers per panicle was found with soil application of multimicronutrients grade-V 400 g followed by foliar application of multimicronutrients grade-IV 1.0 % during both the years of study. The significantly higher number of fruits, average fruit weight and fruit yield per tree were recorded with soil application of multimicronutrients grade-V 400 g followed by foliar application of multimicronutrients grade-IV 1.0 % during the years 2017-18 and 2018-19.

The role of arbuscular mycorrhizal fungi in sweet oranges is well known, but the function of their secondary metabolite, especially the easily extractable glomalin-related soil protein (EE-GRSP), an active fraction of glomalin, is still unclear. The proposed study aimed to analyze the field response of foliar application of exogenous EE-GRSP on tree mycorrhizal development and fruit quality of two sweet orange (Citrus sinensis L. Osbeck) varieties viz., Lane Late Navel (LLN) and Rohde Red Valencia (RRV). Application of EE-GRSP significantly increased the root mycorrhizal colonization and soil mycorrhizal hyphal length in both the sweet orange varieties. The external quality of fruits (fruit weight, polar diameter, and equatorial diameter) also improved in response to foliar application of EE-GRSP in both sweet orange varieties. However, EE-GRSP treatment showed no change in fruit soluble solid content, while it increased the Vc content, solids-acid ratio, fructose, glucose, and sucrose content of sarcocarp in the two sweet oranges varieties. The LLN variety treated with EE-GRSP recorded significantly higher N, P, K, Fe, and Si content of sarcocarp as a mark of nutritional quality, while the RRV variety treated with EE-GRSP displayed a higher concentration of nutrients like Cu, Fe, Si, and Zn in the sarcocarp as compared with the corresponding non-treated control. To the best of our knowledge, this is the first report regarding the improvement in fruit quality of late-ripening sweet oranges (especially LLN) in response to foliar application of EE-GRSP as another potential biostimulant.

The present study was carried out during the seasons of 2014 and 2015 at the Research and Agricultural Experimental Station, King Saud University, Saudi Arabia, to investigate the effects of foliar application of CaCl2 at 1 or 2%, Ca(NO3)2 at 0.5 or 1% and ascorbic acid at 50 or 100 ppm on yield and fruit quality of Ziziphus jujuba trees. All treatments were repeated twice (December 15 and January 15) before harvest date in both seasons. Treatments significantly improved yield and fruit physical characteristics (fruit weight, flesh weight, fruit volume, fruit length, fruit diameter and fruit firmness) in comparison to untreated control in both seasons. Fruit chemical characteristics (TSS, Acidity, total sugar contents, ascorbic acid, and total chlorophyll) were mostly improved by most tested treatments in both seasons over the control (water only). It can be concluded that foliar application with Ca(NO3)2 at 1% would be the best treatment to obtain highest yield, fruit physical and chemical composition of Z. jujuba.

The flowering induction in mango (Mangifera indica L.) orchards is an agricultural practice carried out on tropical regions to obtain fruits out-of-season looking to reach better sale prices. The objective of this research was to evaluate the effect of potassium (PN), ammonium nitrate (AN) and paclobutrazol (PBZ) on flowering induction and fruit production in mango cv. Tommy Atkins. The experiment included fourteen treatments with 2, 4, and 6 % PN, and 2, 3 and 4 % AN applied in combination with PBZ (1 g of a.i. m-1 of canopy diameter), paclobutrazol alone (1 g of a.i. m-1 of canopy diameter), and a control (water), which were arranged in a completely randomized design with three replicates. Results show that floral induction and fruit production were improved: PBZ followed by foliar application PN 2 %, 4 % or 6 % induced flowering 16 days after treatments. Likewise, the major number of emerged panicles were obtained with PBZ + PN 6 %. An increase on fruit weight and size reduction was observed at harvest. PBZ followed by foliar application of nitrates induced flowering and enhanced the number developed panicles in mango cv. Tommy Atkins.RESUMENLa inducción floral en mango (Mangifera indica L.) es una práctica agrícola común en regiones tropicales, tendiente a obtener frutos fuera de temporada para lograr mejores precios de la cosecha. Este trabajo tuvo como objetivo evaluar el efecto de tratamientos de nitrato de potasio (PN), nitrato de amonio (AN) y paclobutrazol (PBZ) sobre la inducción floral y producción de fruto en mango cv. Tommy Atkins. Los tratamientos con PN al 2, 4, y 6 % y AN al 2, 3 y 4 % fueron aplicados solos o combinados con PBZ (1 g de i.a. m-1 de diámetro de copa), PBZ solo y un testigo (agua) bajo un diseño completamente al azar, con tres repeticiones. Se midieron variables de inducción floral y producción de fruto. Los resultados muestran que aplicación foliar de PBZ seguida de PN (2 %), (4 %) o (6 %) indujeron floración 16 días después del tratamiento. El mayor número de panículas emergidas se obtuvieron con PBZ + PN 6 %. Se observó una reducción de peso y tamaño de fruto a la cosecha. El PBZ seguido de aplicaciones foliares con NP y AN induce floración y aumenta el número de panículas desarrolladas en mango cv. Tommy Atkins.

Selection potential based on differential fertility and mortality has been computed for six tribal groups inhabiting different geo-climatic conditions, namely: Sahariya, Mina and Bhil of the State of Rajasthan, north-western India, and Munda, Santal and Lodha of the State of West Bengal, eastern India. Irrespective of the methodology, the total index of selection was found to be highest among Lodhas (0·668), followed by Sahariyas (0·524), Santals (0·462), Bhils (0·386), Mundas (0·353) and Minas (0·334). Incidently, Lodha and Sahariya are two of the seventy-four notified primitive tribal groups of India, and these two study populations show the highest index of total selection, mainly because of a higher embryonic and postnatal mortality.The relative contribution of the fertility component to the index of total selection is higher than the corresponding mortality component in all tribal groups.The analysis of postnatal mortality components indicates that childhood mortality constitutes the bulk of postnatal mortality, suggesting that children under 5 years need better health care in these tribal groups.
